FLUSH VALVE.

Application filed November 27,1922. Serial No. 603,521.

Improvements in Flush Valves; and I do declare the following to be a full, clear, and exact description ofthe same, reference being had to the -accompanying drawings, and to the characters of reference marked thereon, which form a part of this application.

This invention relates to toilet-flush systerns, and is particularly intended as an improvement of that type of device shown in my co-pending application for patent on toilet flush, filed September 5th, 1922,1mder Serial No. 586,308.

The principal object of the'present in ventioii. is to simplify the construction shown in the above identified application, by doing away with numerous parts without altering the principle of operation 'or reducing the'eflicien'cy of the device.

I have also provided a valve operating means which is simpler and more convenient to operate than that of the first type, and

have arranged that the valve member itself may be very quickly and easily removed without disturbing the control or operating mechanism.

A further object of the invention is to produce a simple and inexpensive device and yet one which will beexceedingly effective for the purposes for which it is designated.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings similar characters of reference indicate corresponding parts in the several views? Fig. 1 is a side elevation of a toilet showing my improved flush valve and tank installed in connection therewith.

Fig. 2 is a sectional elevation of the tank and the connected parts.

Fig. 3 is a top plan view of the float-valve with its guide means.

Fig. 41 is a detached view of the valveraising stem.

Referring now more particularly to the characters of reference on the drawings, the numeral 1 denotes the flush tank or reservoir, of desired shape and size and substantially air tight, with which is connected a water supplypipe Screwed into the bottom of the tank is Pspecial T-litting 3, the upper end of said littiiig'haviiigan orilice a conm'iunicati ig with the tank and of smaller diameter than the interior of the fitting. The metal sur rounding said orifice is raised to form a flange or rim-5 which servesas aseat tor a valve-pad 6 of rubber or the like, which is fitted into the "lower end of hollow cylindrical and preferably metallic float 7, said pad being held in place by a screw 8' whose head projects downwardly into the orifice 4 when the valve is seated.

The-lower end of the member 3 isadapted to be connected to the usual forms of flush pipe 9 leading'to the toilet bowl 10. Screwed into the upper end of the member 3 about the float are guide rods 11, which extend upwardly to a point adjacent the top of the tank, and are there connected together and lieldin spaced relation by a ring" '12. The bore of'tliis ring is of sufficieiit size to enable the float to pass therethrough, so that it may bew'ithdrawn from the tank when de- 30 sired upon the removal of a plug 13 fitted *in the upper endof the tank above the ring.

Formed with the fitting 3 in vertical alinement with the orifice 4 are sleeves 14:, one

being above and below the side portion or chamber 3 of the fitting 3, these sleeves forming guides for a vertical rod 15 substantially the samesize as the opening 1, the upper end of which rod is preferably provided with a rubber or other resilient head 16 which is adapted to abut against the screw-head 8. I F

The possible vertical movement of this rod is limited in a downward direction by reason of a shoulder-17 thereon which normally abuts against the upper face of one of the sleeves 1 1, while movement in an upward direction is limited by an adjustable nut 18 on the lower end of therod which is adapted'to abut against the under face of the lower sleeve 1 I v The rod 15 is provided with a vertical slot 19 intermediate the guide sleeves, in which slot, centrally of its ends is located a transversely disposed roller 20 mounted on a pin 21 tired in the rod.

An arm 22-, fixed on a horizontal shaft 23 which is turnably mounted in the member 3 transversely thereof, and parallel to said roller, has a forked portion 2-11. at

its free end, which portion projects into the slot .11) and straddles the roller.

A handle-lever 25 is fixed on theshaft 23 outside the member 3 and extends't'oward and alongside the bowl 10, the normal position of this lever, When the rod 15 is lowered and the valve is seated; being at a slant about 5 below a horizontal line.

A removable cap or plug 26 is fitted in the outer end of the member 35 soias. to aid in placing or removing the arm 22.

The tank is preferably supported by the floor by means. of; a stanchion 27 screwed into a. boss or socket 28 formed with and on the underside of" the member 3?.

A lug. 29'is also provided; on the upperend and. back; face of the tank t'o receive a lag sQreYW 30 extending into a: walhjoist.

In assembling the device, the fitting 3, with the floor, guide rods,. operating lever and: all. other. parts,. areassembled: as a complete unit, the guide rods 11: being then.

slipped up. into the orifice in the bottom of the tank into which the fitting 3 is screwed prior to the accomplishing ofthelatter operation.

In the operation of the device-, the pressure of the Water on. the float 7. when the tank is full holds the float seated.

When it is desired toflush the tank. the lever 25- is raised for its. full. traveh as governed by the possible movement of the rod: 15', which: as. will be evident is raised at the same time This raising ot the nod causes the float to be raisedfrom. its. seat, and it will then float tothe topof. the Water in the tank, descendingas the Water level is lowered;

The float is prevented. from being prematurely drawn back. into its seat withv the ini'ush of Water through the orifice 41. before said floathas a chance torieetoithe surface for two reasons. First, because, the, movement of the rod is intentionally so. great that the float when raised; as, aepossible by saidrod. is above the main. suctional influence of the Water. pouring through the orifice 4 Toaida inminim-laing this influence, the lower corners of? the float are cut. away on a slope, so as to reduce the under-face area thereof; Secondly the rod. lobeing as before stated about the same size as the opening 41,. said; opening is practically closed by the rod. when. the latter is raised so that but very little Water can then enter said opening, and. the suctional influence of. the Water is very slight.v

. V The rod, having. functioned: to. raise the be readily seenthat I have produced such a device as substantially fulfills the objects of the-invention asset forthherein. I

While this specification; sets; forth in. de-

tail the present and. preferred construction ot the device, still in practice such ClEWlfl-- tions. tro n, such detail may be resorted: to asdonot form a departure fromthespirit ot the invention, as definedby the appended claims Having thus described my invention, What.

I.- claim as new and. usetul' and. desire to secure by Letters Patent is:

1. A. flush valve structure comprising a hollow fitting adapted to be interposed; be-

tween. the lower end; of a tank' and a toiletboivlua float. valve toiseat. adjacent the upper end. of. the fitting, a vertical. rod in the fitting below the valve and. adapted. to, engage and raise the same, means for raising the rod,

guide sleeves in. the fitting; for' the latter, a.

shoulder on the rod resting on the upper face of one sleeve when. the rod; is. in. its lowermost position, and an adjustable nut on. the rod and. adapted. to. abut against the under face of the sleeve when the rodhasbeen. raised a predetermined amount.

A. fliislr valve structure comprising a hollow. fitting adapted to: be. interposed between. the lower end, of a tank, and a. toilet bowl}. a floatvalve to. seat adj acent. theupger endlof the fitting. a vertical rod in the fitting below the valve and adapted toellgage and. raise, the same a. pin. extending transversely of. the rod, an. arm. slotted from one end; engaging the pin, a shafit on. which the arm is mounted journaledlinthe: fitting parallel: to the pin... and a. removable. plug in the fitting beyond. tlllfi shaft and. onfthe side thereof away fi'0mthe, rod;

Intestimony whereof I. aflix my signature.
